    It appears to be well made unlike some of their other product.

    Would that be the regular 503 or this HD flavor?

    The early KL503 ones were terrible with that silly unbiased driver transistor.
    The HD ones might be better if all 8 are fed together but not at 300w.
    200 watts PEP would probably be a cleaner output.
    But the proof is in the pudding!
    Who has one of these new ones?
    How is it?
